Cell Organelle Structures and Functions

SC.6.L.14.4 Compare and contrast the structure and function of major

organelles of plant and animal cells, including cell wall, cell membrane,

nucleus, cytoplasm, chloroplasts, mitochondria, and vacuoles.

ESSENTIAL QUESTION: What organelles can only be

found in plant cells and what do they do?

Discovery Education:

Parts of a Cell

I Do- Guided Notes

Function: Control center of the

cell, holds genetic information

(DNA).

Found: In ALL Eukaryotic Cells

(Both Plant and Animal)

The Nucleus

Cell Membrane

Function: Allow items to enter/exit

the cell. Keeps bad stuff out.

Found: ALL Cells (Plant and Animal)

Cell Wall

Function: Rigid wall helps plants keep their shape, keep badstuff out

Found: PLANTS but not animal cells.

Allows plants to grow tall, like bricks in a wall.

Chloroplasts

Function: To make food (glucose) through photosynthesis.

Found: ONLY in plant cells!

*Chlorophyll (green) absorbs sunlight.

Mitochondria

Function: Convert chemical energy stored in glucose into energy (Cellular Respiration)

Found: In ALL Eukaryotic Cells (Plant and Animal)

More mitochondria are found

in muscle cells than skin.

Cytoplasm Function: Jelly-like material inside the

cell membrane. All organelles can be found here.

Found: ALL Cells (Plant and Animal)

Vacuole

Function: Stores water & Transports waste

Found: LARGE in plants, small in animals

YOU DO TIME!

You Do Question #1

For her science project, Suzanne made an animal

cell using a rectangular shoe box, pipe cleaners,

and construction paper. One comment that the

teacher made was that Suzanne should not have

used a shoe box. Why did the teacher make this

comment?

a) Animal cell shape is more round than rectangular.

b) Animal cell shape is more like a stop sign than a

rectangle.

c) Plant cell shape is more round than rectangular.

d) Plant and animal cells have a similar shape.

You Do Question #2

Which organelle is nicknamed “the

powerhouse” of the cell and generates the

cell’s energy-rich molecules?

a) Nucleus

b) Chloroplast

c) Mitochondrion

d) Cell Wall

You Do Question #3

Four cells were examined under the microscope. The following

table shows the organelles that were identified in each cell.

Based on the table above, which of the following is the best

conclusion?

a) Cells A and B are plant cells.

b) Cells B and D are plant cells.

c) Only cell B is a plant cell.

d) Only cell C is a plant cell.

CELL ORGANELLES INDENTIFIED IN EACH CELL

A nucleus cell membrane mitochondria cytoplasm

B cytoplasm nucleus chloroplast large vacuole

C mitochondria small vacuoles nucleus cell membrane

D chloroplast mitochondria cell wall nucleus

Many scientists claim plants are more

complex than animals based on the

differences in plant and animal cells. What

evidence can scientists use to support their

claim?
